Love this 3D puzzle - the whole family love it, from 6 to 67. Already ordered the Epic and the Twist based off of this puzzle.

By curiosity, I tried it before giving it to my grand-daughter and I kept it a few days longer in order to play with it. She is 8 eight years old and found that was a cool gift.

We love it ! the whole family plyed ... and most of us got addicted. Our 7 yrs-old daughter wants to order a another one from Santa.

Our nephew loved this as a gift! I was worried that it might be a frustrating game but he called us the other day thrilled that he had gotten through it. His parents were also very pleased he got a "thinking" toy. Definitely recommend.

I bought this for my girlfriend and I to play with before passing it on to a lucky kid. As an adult I feel the level of challenge could be a tad higher; on the other hand, kids that are too young just won't have the motor skills (or patience?) to make it all the way through the maze. I don't know enough about kids to say what a minimum age might be. The toy is solidly built, but it has to be handled carefully to avoid scratching the exterior. As mentioned by others, the biggest flaw is the numbers, which are simply molded into the plastic pieces, making them a bit hard to read. The Perplexus logo molded into each side of the globe occasionally interferes with one's line of sight. Neither flaw is a big deal. The package mentions two other models (Swervy Mervy and Brain Cramp,) but they don't seem to be on the market. I paid $20 in the US, which is a great value for such a clever toy that's fun for both kids and adults. The Canadian price is, as usual, a bit less attractive. Recommended!

My 8 yr old son received this and a DS for Christmas. This toy has had 5X more time devoted to it. It was a smash hit with family wanting to know where I found it. The biggest problem with this toy seems to be that it is a void of time-look up and realize you have been playing with it for an hour!!! My son now wants to know where we can get other toys like it...

Bought this for the kids for Christmas and have a very hard time putting it down long enough to wrap it. Great game for kids in the over 8 age group.
